摘　　要：随着地质找矿工作的深入和找矿难度的加大,对地球化学异常评价提出了更高要求,研究提取地球化学勘查新指标对提高找矿成功率意义重大。通过对乌努格吐山斑岩型Cu-Mo矿床、罕达盖矽卡岩型Fe-Cu矿化以及垦山多元素组合异常REE指标的研究,发现矿致异常与未见矿异常、斑岩型矿化与矽卡岩型矿化REE各项指标存在明显差异,矿化体赋存部位与REE指标空间位置吻合,这一发现使得应用REE评价地球化学异常成为可能。With the increasing depth and difficulty of geological exploration,the requirements of geochemical anomaly evaluaion have become higher and higher,and it is of great significance to find new geochemical indicators to improve the success rate of ore-prospecting.The authors studied REE indicators in the Wunugetushan porphyry Cu-Mo deposit,the Handagai skarn type mineralized bodies and the Kenshan multi-element anomalies,and the results show that REE indices are obviously different between ore-related anomalies,barren anomalies,porphyry mineralization and skarn mineralization.This discovery makes it possible for us to use REE to evaluate geochemical anomalies.
